“I’m”, “You’ve”, “It’s”, “We’d” …
The verb to contract means to make something smaller, which is exactly what a contraction is! Contractions are short ways to say or write two or more words at the same time. While very common in speech and informal writing, contractions are not used in formal writing. The most common function of a contraction is to replace a vowel with an apostrophe:
I am →I’m
We are →We’re
Sometimes a contraction replaces more than one letter, and sometimes a contraction could have two possible non-contracted forms:
He will →He’ll
I have →I’ve
She had →
She would →
There are many contractions that are regularly used in English. Note that it is always correct to use the non-contracted form when speaking or writing – contractions just make speaking and writing flow more quickly.
